you dont fight morganthe YET. there will be more worlds leading up to you fighting her. but you dont fight her in celestia. it'll be like when you had to go through all the worlds just to fight malistaire
Morganthe is the new "Malistaire" of the new storyline currently started ith Celestia and we wont be fighting her until like say 4-5 worlds Can't wait! Hope I helped! :) Fire is the True Balance!
